3. Ronnie is building a tower out of blocks. There are 38 blocks in the bottom row. Each row above the bottom row has 3 fewer blocks than the row below it.
(a) Write an iterative rule to model the sequence formed by the number of blocks in each row.
(b) The top row has 5 blocks. Use the rule to determine how many rows are in the tower. Show your work.
Answer:

Answer 1

Answer: 38-(3*11)=5

The 11 is how many rows there are. I think that's right, not sure

Ruby ate 1/3 of a pizza, and Angie ate 1/5 of the pizza. How much of the pizza did they eat in all?

Answers

Find common denominators. Multiply 5 to numerator and denominator of 1/3, and 3 to the numerator and denominator of 1/5

(1/3)(5/5) = 5/15

(1/5)(3/3) = 3/15

Add

5/15 + 3/15 = 8/15

Ruby and Angie ate 8/15 of the pizza.

hope this helps

i think it is 8/15 of the pizza

Halfway through a bus route, 23 students have been dropped off and 48 students remain on the bus. Write an equation to determine whether there are 61 or 71 students on the bus at the begginning of the route.

Answers

Answer: The required equation is

$x=23+48\n\Rightarrow\ x=71$

Thus, there are 71 students on the bus at the beginning of the route.

Step-by-step explanation:

Given: The number of students dropped off = $23$

The number of students remain on the bus = $48$

Let 'x' be the total number of students in the bus then we get the equation as

$x=23+48$

On adding 23 to 48, we get 71

Hence, $x=71$

Therefore, There are 71 students on the bus at the beginning of the route.

48+23=71. So seventy one students were on the bus then 23 were dropped off leaving 48 remaining

Which of the following is an equation of the circle with its center at (0,0) that passes through (3,4) in the standard (x,y) coordinate plane?F. x – y = 1
G. x + y = 25
H. x^2 + y = 25
J. x^2 + y^2 = 5
K. x^2 + y^2 = 25

Answers

The distance from the origin to the point (3,4) is the radius of the circle.

That distance is √(3² + 4²) = √(9 + 16) = √25 = 5 .

The equation of a circle centered at the origin is

x² + y² = (radius)²

So this circle is [ x² + y² = 25 ]

That's Choice-'K'.

The graph shows the solution to which system of equations?A)
y = x + 2 and y = -x - 4
B)
y = 3x + 7 and y = x + 12
C)
y = 2x - 3 and y = −2x + 1
D)
y = -x + 4 and y = −2x + 5

Jackie sold 48 pints of lemonade at her stand. How many quarts of lemonade did she sell? (1 quart = 2 pints)

Answers

Since 1qt is equal to 2 pints, and Jackie sold 48 pints, she sold 24 quarts.

OK. Since One quart= 2 pints, divide the number of pints (48) by 2.
48/2=24
24 is the answer for the number of quarts.
